AI Technical Summary
Technical Problem
RFID tag readers face challenges in effectively communicating with multiple tags due to interference and limited transmission power in unlicensed frequency spectrum bands, restricting the distance and accuracy of data transmission.
Method used
The RFID tag reader employs a licensed cellular communication spectrum for higher transmission power, uses antenna beam formation and steering, frequency hopping, and CDMA modulation, and coordinates with multiple readers to improve communication range and reduce interference.
Benefits of technology
Enhances communication distance and reduces interference, enabling efficient reading of RFID tags at greater distances with improved accuracy and throughput.

Abstract
A radio frequency identity (RFID) tag reader. The reader comprises an antenna; a radio transceiver coupled to the antenna, wherein the radio transceiver is configured to transmit and receive in a cellular radio frequency band; a memory; a processor coupled to the radio transceiver and to the memory; and an application stored in a non-transitory portion of the memory. When executed by the processor, the application sends a query message via the radio transceiver and the antenna to a plurality of RFID tags; and receives a plurality of query response messages via the radio transceiver and antenna from the plurality of RFID tags, wherein at least some of the query response messages are encoded using different pseudo-random number (PN) codes and receiving the plurality of query response messages comprises demodulating at least some of the query response message using different PN codes.
